If you double-wrap every piece with bubble-wrap, then fill the bottom of your shipping box with styrofoam pellets, then lay all the pieces on the styrofoam pellets, then fill the box with styrofoam pellets, then double-box it, it should be safe enough to ship by Greyhound...but JUST TO BE SURE...INSURE it for the total selling price, the price of the bubble-wrap and styrofoam, the cost of the materials to make the shipping box, your labor, the shipping price, and the price for the insurance. That way you're covered if it gets damaged in shipment, That way you've sold it to the buyer -- or to Greyhound. Either way, you have a sale!
